If you accidentally add diesel to the gasoline car, the problem will be more serious. Theoretically, due to the different combustion methods of gasoline and diesel, cars may shake, exhaust gas may emit black smoke, and some engines may not catch fire at all.

When this happens to the car, the owner must not drive forcibly, which will only damage the whole oil system of the car and may lead to engine overhaul. In this case, the owner should contact a professional factory or 4S shop as soon as possible, clean the fuel tank and oil system, and check the engine to ensure that it is intact.
